A ball of mass 3.0 kg is tied to the end of a 50-cm length of string. The ball and string are swung in a circle in a vertical plane at constant speed V, which is the minimum speed necessary to keep the string taut at all times. The center of the circle is a distance - 190 cm above the floor. Suddenly, the string is released at the instant the ball is at the top of the loop. How far to the right of the center of the circle does the ball hit the ground? 0.0 cm

150 cm

210 cm

230 cm

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
